题 目 太阳能路灯控制器的设计摘要：控制器可以说属于全部太阳能路灯系统的最重要的部分，这篇文章使用了基于Atmega48 单片机的控制器，这个原理是使用 PWM 脉冲调制控制的技术来达到对蓄电池电压充电电流等信息数据进行检测，控制开关管的关断，来实现充充电控制和保护控制功能，通过此次试验，为了让路灯系统使用起来更加安全可靠。关键字：太阳能控制器;Atmega48 单片机;PWM;充放电控制Design of Solar Street Lamp ControllerABSTRACT: Controller can be said to be the most important part of all solar street lamp systems. This paper uses the controller based on ATMEGA48 single chip computer. This principle is to use PWM pulse modulation control technology to detect the parameters of battery voltage, charging current and so on, and to control the switch off to realize charging.Charging control and protection control function, through this test, in order to make the street lamp system more safe and reliable.Key words: solar controller; Atmega48 MCU; PWM; charge and discharge control目 录第 1 章 绪论...................................................................................................................................................41.1 LED 太阳能路灯系统的组成..........................................................................................................41.2 路灯控制器的设计原则...................................................................................................................4第 2 章 系统设计...........................................................................................................................................42.1 路灯控制器硬件及软件设计...........................................................................................................42.1.1 路灯控制器电源输入部分和输出部分.................................................................................42.1.2 路灯控制器数据采集显示控制部分.....................................
